[vlc-devel] [RFC] [PATCH 0/4] VLC object resource tracking

[Rémi Denis-Courmont]

	Hello,

This adds a simple resource tracking stack for module instances, with view to 
simplifying clean-up paths (especially poorly tested error handling).

What this is:
- A simple way to tie resources to a module instance, so they get freed 
automatically.
- A very similar (though much simpler) system than Linux kernel devres.

What this is NOT:
- A garbage collector.
- A complete patchset. Only usage example is malloc/calloc for access p_sys.

----------------------------------------------------------------
Rémi Denis-Courmont (4):
      module: pass VLC object to vlc_module_unload()
      objres: introduce object resources tracking
      objres: add simple memory allocation
      access: allocate p_sys vlc_malloc/vlc_calloc
